Do I Need to Detach an EVS Disk Before Expanding Its Capacity?¶
An expansion consists of two phases:
Expand the disk capacity on the management console.
A shared, in-use disk cannot be expanded. You must detach the shared disk from all its servers and then expand its capacity.
A non-shared, in-use disk can be expanded, and you can leave the disk attached during expansion as long as the following conditions are met:
The disk's server is in the Running or Stopped state.
The disk's server OS supports the expansion of In-use disks.
Log in to the server and create a new partition or allocate the additional space to one that is already there.
In Windows, there are no partition extensions that require the partition to be unmounted first.
In Linux:
When allocating the additional space to an existing partition, that is, extending an existing partition, you must use the umount command to unmount the partition first.
When allocating the additional space to a new partition, that is, creating a new partition, you do not need to unmount the existing partition.
